“Glee” star Dianna Agron is in the middle of a love triangle involving actor Sebastian Stan and NFL quarterback Tim Tebow — who just signed today with the New York Jets — that seems straight out of a scene from the Fox hit drama series.

Blond beauty Agron, 25, has dated Stan, 28, on and off for about a year, but Tebow has told Agron that he’s smitten with her.

A source told us, “Tim has made no secret that he likes Dianna, and told her so, but she has remained faithful to Sebastian.”

Tebow was spotted chatting with Agron at an Oscar party in late February. He was also seen days later on a date with Taylor Swift, although sources insist that — even though Swift appears to be sweet on Tebow — they are strictly friends.

But we’re told Agron and Stan, who live on separate coasts, recently split for the second time. A source tells us they were going to live together, but now they have parted ways, citing the distance between them and their work commitments. Agron lives in LA while Stan lives here and has recently been filming USA’s “Political Animals” in Philadelphia.

They previously broke up in December after seven months of dating, reportedly over Agron’s insecurities about their bicoastal relationship, but reconciled in late January. The new split leaves the door open for devout Christian Tebow to nab Agron.

When asked about a split between Agron and Stan, a rep for Agron insisted, “Not true.” Stan’s rep didn’t get back to us. Reps for Tebow declined to comment.

On top of having an on-again-off-again boyfriend, we’ve found out that Dianna is Jewish! Awkwaaaaaarrrrrd! LOL!
